The 'View Representation' column is not available in the Part Navigator.
Specifically this column may be needed to see the 'Snapshot' icon in the
column.
For example: 'Snapshot' is turned ON for one of the drawing views.
The Snapshot icon can be denoted in the 'View Representation' column of the
Part Navigator. But the 'View Representation' is missing in the list as an
available column to be added to the Part Navigator.
Solution
This column is not available in base NX10.0.0.
Upgrade to the latest maintenance release and maintenance pack of NX10 to have
the 'View Representation' available as a column in the Part Navigator.
